Getting the left property of an LI element in jQuery? -

-

I have a dynamic list of LI inside of UL.

I am trying to be competent in any way to 'track' the last list of ul, in which there is a final category.

I thought that if I could test against a number of numbers for the left property of the original, I would say, -500, then I could have done what I had to do.

The problem is that I can not get that property.

Is it possible or override parents (in this case UL)?

If you want a left position relative to the page, then you do so It can: 

  var left = $ ('ul li.Last') offset (). Left; According to

or their parents, do this: 

  var left = $ ('ul li.Last'). Event (). Left;      
  Example:

Obfuscating Python code? -

I'm looking for a way to hide my Python source code. print "Hello World!" How can I encode this example so that it is not human-readable? I have been asked to use Base 64 but I'm not sure how. itemprop = "text"> It is limited only, first level ambiguous resolution, but has built-in: byte-code in Python Is a compiler for: dragon-o-m py_compile & lt; Your program.py & gt; creates a .pyo file with a byte-code, and where the docstrings are removed, etc. You can rename .pyo with the .py extension, and python & lt; Your program.py & gt; runs as your program, but it does not have your source code. PS : If your program blur modules like this, you need to rename them with the .pyc suffix (I Not sure it will not break a day), or you can work with .pyo and run them with python -o ... .pyo ( Import should work). This will allow dragon to search your modules (otherwise, Python looks for the .py module).
